Paint Storage Problems - Paint Skinning
|
|
|
|
|
A ‘‘skin’’ layer appears on top of the paint in a container. | |
|
|
|
Most common on air-dry type paints. Paint surface hardens with exposure to oxygen in the air. | |
CAUSES:
|
|
|
Paint can (container) not sealed with the lid securely. | |
|
|
|
Prolonged storage in excessive temperatures. | |
|
|
|
Paint volume in the can decreased, allowing more space for trapped air (air-dry type). | |
|
PREVENTION:
Securely seal the paint can (container) with the lid and store it in a dark, cool place, 68 °F (20 °C) or below.
|
|
CORRECTIVE ACTIONS:
Dispose of the paint according to local regulations.
